I've seen a few posts stating problems with Brasero.I stopped using Ubuntu 8.10 on my systems to run only LM now because LM burns and runs nvidia 3D .Well LM brasero use to burn until today, so I'm perplexed as to why and what changed.I now get the same deadly error as ubuntu 8.10 , not enough space on empty media.

Try removing your current version of Brasero using Synaptic, mark for complete removal. Install the updated version that Husse has provided a link to. Turn off the plugins in Brasero. This should get things going again. Another work around is to use the default Gnome burning program.

If it does not help to do a complete reinstall I think this is the problem

Session error : The drive seems to be busy (maybe check you have proper permissions to use it) (brasero_burn_record burn.c:2270)

In "the early days" I encountered an error with CD/DVD that had something to do with permissions but I can't remember exactly what or the solutionWith some luck you can find it using Advanced search, my user name searching for "permissions CD"
